Beta-glucans
Beta-glucans are a type of soluble fiber from cereals (oats, barley), fungi (yeast, mushrooms), and seaweed with distinct biological effects depending on source. A-GRADE evidence for blood glucose improvement (98 RCTs, 538 participants, moderate effect) in diabetes and metabolic health. B-GRADE for HbA1c, apolipoprotein B reduction, URTI risk reduction, and fatigue. CEREAL beta-glucans (oat, barley) have FDA/EFSA health claims for cholesterol lowering (3g/day). FUNGAL beta-glucans (yeast, mushroom) are immunomodulatory. One of the few fibers with robust clinical evidence for metabolic benefits.

L-carnitine can relieve leg pain in people with peripheral artery disease (PAD) and treat some aspects of metabolic syndrome. Although it’s often also used for fat loss, its effectiveness for that is questionable.
Vitamin D

Vitamin D is a fat-soluble vitamin that our skin synthesizes when exposed to the sun. It benefits us in many ways, from bone health to mood.
Niacin (Vitamin B3)
6 shared conditions · 117 outcomes
Niacin is a form of vitamin B3. Supplementation with niacin (nicotinic acid) can improve cholesterol levels; however, niacin's inability to reduce cardiovascular disease risk and its association with adverse effects make its use controversial.
Resveratrol
6 shared conditions · 318 outcomes
Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.
